BUTTON.

Application filed November 12, 1923. Serial No. $74,167.

To all whom t may concern.'

Be it known that l, HERBERT T. JENKINS, a citizen of the United States, residing at Portsmouth, in the county of Rockingham and State of New Hampshire, have invented new and useful Improvements in Buttons, of which the following is a specification.

This invention relates to buttons, and more particularly to that class of buttons used on shoes, gaiters, etc, and whichY comprise a met-al loop formed of wire, one end of which is extended to form a shank and is embedded and projects through in a head of hardened plastic material such as papiermch and similar compositions. The shank is of approximately the same diameter throughout and terminates in a iange on the outer end thereof.

In buttons of this class the wire forming the shank extendingthrough the head is 1iiable to become loosened so that the shank will twist in the head, and the head will be liable to crack and otherwise become useless. Moreover if Vthe hole for the wire shank is made small enough so that the wire forms a very tight fit therein, the head is liable to be split when the wire is driven therethrough or will split afterwards in use.

1t is the object of this invention, therefore, to construct a button of the class set forth wherein the shank extending from the loop of the button through the head is securely anchored in the headso that it will not twist, and moreover the anchoring means embodiedpin this invention are of such form and are so positioned on the shank that while anchoring the shank in the button head firmly, both against rotation and longitudinal displacement, the button will not become split when the wire is driven through the head and the loop formed thereon as hereinafter described. Y

The invention consists, therefore, of abutton such 'as hereinafter described and particularly as pointed out inthe claims.

Referring to the drawings: Figure 1 is a plan view of my improved button.

Fig. 2 is a front elevationof the same. 3 is a section of the head of my improved button and a front elevation of the wir@` forming the loop and shank.

Fig. 4 is a sectional elevation taken on line 1 4 of Fig. 1.

Fig. 5 isa front elevation of the wire fromV which the loop and shank are formed,` the same being broken away to savey space.

Fig; 6 is a front elevation of a modified form of wire.

Fig. 7 is a sectional plan takenron the line 7-7 of Fig. 5.

Fig. 8 is a detail sect-ion taken on line e-s of Figa 1 Like numerals refer to like parts throughout the several views of the drawings. i

In the drawings, eXcepting Fig. 6,1() is the button head which in practice is preferably formed of hardened plastic material such as papier-mch, although this inventilon is not confined'to any Vparticular material forming they head. The' head 10 has a hole 12 kpunched'therethrough and preferably countersunk at the opposite ends'l?)` and 14; thereof. 15 is a wire with aflange.

16 on its upper end; 17 and 18 are lockingV members providedk upon the wire 15, said locking members being oppositely disposed.

Thev locking members are preferably tapered at their opposite ends and alsor aretapered from the central portion inwardly toward the wire, thus forming oval shaped wedges. Each ofthe locking members 17 and 18 are 'spaced apart from the upper j end of the wire 15 and one of the locking rInernbersl' is positioned at a `greater' -dis-V tance from the under side of the flange 16l Athan is the other vlocking membei'18. AThe' button is manufactured by driving the wire 15 through the button head in the hole 12 and then''formed' in -the shape of a loop'f19 as illust-rated in Figs@ and 15in a manner v well known to those skilled in the art.

lNhen the wire 15 is driven through the head of the button, the, locking projections are being driven intothe head ofthe buttonand in the completed button a portion of the head is locatedv between, the upper ends of each of said locking members andV the lower side of the flange 16. rlhe portion 2O within the head 10 forms a shank.

It will be seen by this construction and the method of manufacture that it is unnecessaryto have the shank 2O '.t'orni such a tight lit in the` hole 12 as would be the case if the locking projections were not provided, thus the shank is firmly locked in the button head Without splitting the same. The lower ends of the locking members, it Will be noted, are spaced apart from the under side ot the head and the said locking members are located entirely Within the head o1" the button.

It Will be noted that the outer edge ot each of the locking members is inclined toward the opposite ends of said members as Well as the sides thereof, as illustrated in F ig. 8, thus the forcing apart of the material to allow the locking projections to enter the same vis comparatively gradual.

The shape and location of the locking members contributes to the successful insertion of the Wire forming the loop and shank Without splitting the button and also contributes to the firmness oi location of the shank Within the button, and the splitting ofthe heads of the button is reduced to a negligible quantity While the loop is firmly aliiXed to the head, both as to resistance to rotation of the shank in the head and movement of the shank longitudinally thereof Within the head.

It is evident that Without departing from the spirit of my invention a single locking member may be employed instead of a pair of locking members as hereinbefore described and as shown in the drawings and some of the claims are drawn with this construction in View.

It will be noted, that as the lower end of the locking member 17 is nearer the lower end of the wire 15 than is the lower end of the locking member 18, the locking member 17 Will begin to enter the head of the button before the locking member 18, and Will be entirely enclosed Within the button head before the locking member 18 is so enclosed and thus the strain upon the button, tending to split the same during the insertion ot the Wire 15, is lessened.

In Fig. 6 a modied form of my invention is illustrated in Which 15 is the Wire and 16 the iiange on its upper end. Upon this Wire are provided locking members 17 and 18, said locking members being oppositely disposed and inclined at an angle to the longitudinal median plane of the Wire 15. These locking projections are preferably tapered as in the form of lockingprojections 17 and 18 hereinbe-ore described. The Wire 15 and its flange 16 with the locking projections 17 and 18 are forced into the head and an eye is formed on the Wire in the saine manner as hereinbefore set 'forth in relation to the Wire 15 and the loop 19.
